ll'Claims. (Cl. 222-540) This invention relates to a container arranged with a spout in an end wall of the container adapted to dispense liquids, such as lubricating oil, lighter fluid and the like, and particularly to securingthe spout in the container end wall.

It has been the practice to secure a tapering spout in a container end wall'by providing the container end wall with an annular discharge neck and the spout with an enlarged cup-like base atthe larger end to fit over the container neck and the base is secured to the container neck by beading together juxtaposed portions of the neck and base.

Another knownmethod of securing the tapering spout in the containerend wall is toprovide the end wall with a discharge neckarranged with an enlarged annular mouth portion and the spout with a shoulder spaced from the larger end positioned in the discharge neck of the container with the shoulder of the spout abutting the bottom wall of the. enlarged annular mouth portion and secured therein by crimping the side wall of the enlarged annular mouth portion over the shoulder of the spout.

The disadvantages of these known methods of securing a spout in the end wall of a container are numerous and the most basic disadvantages arethe number of steps required in forming the discharge neck and base portion of the spout which will increase the cost of manufacture; the discharge necks will prevent stacking of'the container bodies upon each other for storage prior to securing the spouts to the container bodies; and it is not possible to produce a tight seal between the neck of the container and the spout.

It is an object of the present invention to secure a spout in the end wall of a container without the disadvantages of the prior known methods byproviding a depressed portion in an end wall of the container arranged with a discharge opening aud the walls of the depressed portion formingan annular -channelor groove, and a spout having a flange adjacent to a cylindrical end portion of the spout 'engaged'in the discharge opening with the flange above the groove in the depressed portion of the container end wall, and the spout forced into the depressed portion to flatten out the wallet the depressed'portion adjacent to the discharge openingand impinge the edge of said wall against the cylindrical end portion of the spout below the flange.

It is another object of the invention to arrange the impinging edge of the depressed portion with spaced notches to provide a uniform snug fit between said edge and the cylindrical end portion of thespout.

It is a further object of the invention'to arrange the underface of the spout'flange with an annular groove to compensate for the compression ofsealing means interposed between said underface and the depressed portion of the container end wall to provide a liquid tight seal between the spout and container end'wall.

Another object of the invention isto provide the spout flange with a taperingor beveled edgecorresponding to.

Other objects and advantages of the invention will'be set forth in the detaileddescription-of the invention.

The embodiment of the invention shown in Figures 1 to 4, inclusive, comprises a sheet'metal container .body including a side wall 10 and end walls 11 and 12 secured to the opposite ends of the side wall in anysuitable'manner, such as rolling or crimping together the edge portions of said walls. The end wall 11 constituting the top of the container is arranged with a depressed portion in the center of said wall comprising an inwardly taperingor declining wall portion 13 adjoining the end wall.12 and an outwardly tapering or inclining wall portion 14 extending from the wall port-ion 13 to a discharge opening 15in the center of the depressed portion. The walls;13 and 14 form the depressed portion of annular channel or groove shape in cross-section, as shown at 16 in Figures 2 and 3. The depressed portion is'of anydesired shape and is shown as circular. The edge of the wall portion 14 forming the opening 15 is arranged with equidistantly spaced notches 17 for a purpose to be hereinafter described.

A spout is secured in the discharge opening 15 and comprises a tapering body 13 having a tapering bore 19 therein closed at the smaller end by the material ofithe spout, as shown at 20. The smaller end of the spout is .also provided with a removable closure .cap 21 to close the bore when the closed end 20 is punctured, as shown in Figure 6. The larger end of the spout is arranged with a cylindrical portion 22 having a beveled edge 23 to facilitate engagement of the spout into the opening 15. Between the body 18 and cylindrical portion 22, there is provided on the spout a flange having the upper-face sloping downwardly from the body 18 in an arcuate direction, as shown at 24, and the edge beveled inwardly or tapered from the upper-face to the undertace, as shown at 25. The taper 25 corresponds to the angle of inclination-of the depressed portion wall 13 to provide atight 'fit be'tween'the end wall lft'and the spout flange and'faci-litate securing the spout in said end wall. Theunderface of the spout flange is arranged with an annular groove 26 between the edge and portion 22 for a purpose to be hereinafter described. The material of the spout is softer than the material of the container, such as lead alloy or plastic such as polyethylene. The diameter of the spout portion 22 is slightly less than the diameter of the opening 15 in the position of the depressed portion 13, 14 shown in Figures 2 and 3 to permit ready engagement of said spout portion into the opening.

Prior to engaging the spout portion 22 in the opening 15, an annular sealing gasket 27 of suitable material, such as composite cork or rubber, is engaged on the spout portion 22 against the underface of the spout flange. The gasket will span the groove 26 and terminate inwardly of the edge formed by the underface and beveled edge 25, as shown in Figure 2.

The spout having the gasket thereon is engaged in the opening 15 and subsequently pressure is applied to the spout flange in a direction toward the container end wall 11. The pressure is shown as being applied by a hollow plunger 28 having a bore slightly larger than the larger end of the tapering spout body 18 and a head 29 adapted to engage the juncture between the spout body and upper face of the spout flange, as shown in Figures 3 and 4. The initial pressure applied to the spout flange partly forces a portion of the gasket 27 into the groove 26, as shown at 30 in Figure 3, and the continued pressure forces the depressed portion wall 14 into a fiat or horizontal plane thereby decreasing the diameter of the opening 15 and impinging the edge of the depressed portion wall 14 forming said opening into the spout portion 22, as shown at 31 in Figure 4. At the same time, the gasket is compressed between the spout and depressed portion, as shown at 32 in Figure 4. The notches 17 facilitate decreasing the diameter of the opening 15 and assure a uniform impingement between the edge of the depressed portion 14 and the spout portion 22. The groove 26 will prevent excessive pressure from being applied to the depressed portion wall 14 and prevent forcing said wall 14 below the horizontal plane and collapsing of the container end wall 11 by receiving a portion of the gasket in the initial step of applying pressure without impairing the sealing efficiency of the gasket. When the pressure is removed from the spout flange by raising the plunger 28, the depressed portion wall 14 will remain in its horizontal position by the impingement of the edge thereof with the spout portion 22 and the stiffness of the material of said wall 14. The spout is also secured in the depressed portion of the container end wall by the tight fit between the beveled edge 25 of the spout flange and the depressed portion wall 13.

In Figure 7, there is shown a modified form of depressed portion in the container end wall 11 wherein the edge of the wall 14 forming the opening 15 is even or smooth and not interrupted by the notches 17, as shown at 33.

In Figures 8 and 9, the gasket 27 is replaced by a sealing compound applied to the groove formed by the depressed portion walls 13 and 14, as shown at 34 in Figure 8. When pressure is applied to the spout engaged in the opening 15 as described hereinbefore, the sealing compound is forced into the groove 26 and extends in a film between the depressed portion and spout, as shown at 35 in Figure 9.
